It's an unshrouded, through-hole solder part with push-pull mating — a workhorse for board-to-board or wire-to-board interconnects where you need a straight, unkeyed pin strip. The 31-position count is less common than 30 or 32, so confirm your BOM circuit count matches exactly before committing. Rated 5 A per circuit at 110 V, with 30.0µin (0.76µm) gold or Gold GXT plating on the mating surface. The phosphor bronze contacts and UL94 V-0 black housing round out a standard industrial-grade build. ## Board layout and footprint The 0.100\" (2.54mm) pitch matches the standard 0.1-inch grid, so it drops onto breadboard or perfboard without layout surprises. The 0.225\" (5.72mm) post length gives enough through-hole depth for a 1.6mm PCB with room for a solder fillet. Overall contact length is 1.225\" (31.12mm), with the mating pin extending 0.900\" (22.86mm) above the insulation — that's a long pin, so check your stack-up height if you're mating to a receptacle in a tight enclosure. There's no keying shroud, so the mating connector must provide its own polarization if needed.","metaTitle":"Amphenol BERGSTIK II 91276-131HLF, 31-Pin 2.54mm Header, 5A","metaDescription":"Amphenol BERGSTIK II 91276-131HLF, 31-position single-row male pin header, 0.100\" (2.54mm) pitch, through-hole solder, 30µin gold GXT plating, rated 5A at 110V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"specifications":{"Style":"Board to Board","title":"91276-131HLF","Series":"BERGSTIK® II","Package":"Bag","Shrouding":"Unshrouded","Termination":"Solder","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Push-Pull","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Voltage Rating":"110V","Contact Material":"Phosphor Bronze","Insulation Color":"Black","Insulation Height":"0.100\\\" (2.54mm)","Base Product Number":"91276","Number of Positions":"31","Contact Length - Post":"0.225\\\" (5.72mm)","Current Rating (Amps)":"5A","Overall Contact Length":"1.225\\\" (31.12mm)","Contact Finish - Mating":"Gold or Gold, GXT™","Contact Length - Mating":"0.900\\\" (22.86mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4298","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/92307fceaf3148c5e5d11d6ec0b95cb1.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/91276-131HLF/alternatives.json"},"ai":{"faq":[{"question":"What is the current rating of the 91276-131HLF?","answer":"Rated 5 A per circuit at 110 V.
